Alternative biochemistry collectively refers to an assortment of astrobiology theories and hypotheses in which life is based on chemical systems other than those used by currently known forms of life. Proponents of such theories sometimes use the expression carbon chauvinism to disparage the assumption that carbon molecules are necessarily the basis for all life. Up to this point, however, no non- carbon based life-form has been discovered. ...more on Wikipedia about "Alternative biochemistry"
Astrosociobiology (also referred to as exosociobiology and xenosociology) is the speculative scientific study of extraterrestrial civilizations and their possible social characteristics and developmental tendencies. The field involves the convergence of astrobiology, sociobiology and evolutionary biology. Hypothesized comparisons between human civilizations and those of extraterrestrials are frequently posited, placing the human situation in the same context as other extraterrestrial intelligences. Whenever possible, astrosociobiologists describe only those social characteristics that are thought to be common (or highly probable) to all civilizations. Thus far, it is entirely theoretical. ...more on Wikipedia about "Astrosociobiology"
Back-contamination is the informal but widely-employed name for the introduction of microbial extraterrestrial organisms into Earth's biosphere.

Shklovskii, and Hermann Oberth are three notable scientists who have seriously considered the possibility of extraterrestial visitations in Earth's past.

The zoo hypothesis is one of a number of suggestions that have been advanced in response to the Fermi Paradox, regarding the apparent absence of evidence in support of the existence of advanced extraterrestrial life. According to this hypothesis, aliens would generally avoid making their presence known to humanity, or avoid exerting an influence on our development, somewhat akin to zookeepers observing animals in a zoo. ...more on Wikipedia about "Zoo hypothesis"
